CO2 laser cutting machine for battery shell shaped parts: an innovative tool in energy technology manufacturing

The hydrogel material made of nano cellulose and algae was tested as an alternative and more environmentally friendly building material for the first time. This study from Chalmers Institute of Technology and the Wallenburg Wood Science Center in Sweden demonstrates how to 3D print rich sustainable materials into various building components, using much less energy than traditional building methods...

Recently, a research team from the University of Massachusetts Amherst has pioneered a new technology that uses laser irradiation on concentric superlenses on chips to generate holograms, thereby achieving precise alignment of 3D semiconductor chips.This research result, published in the journal Nature Communications, is expected to not only reduce the production cost of 2D semiconductor chips, bu...

SPIE, the international society for optics and photonics, has welcomed 92 new Senior Members from 19 countries. SPIE Senior Members are Society Members of distinction who are recognized for their professional experience and technical accomplishments, their active involvement with the optics community and with SPIE, and for significant performance that sets them apart from their peers.The newly rec...

In the last century, the improvement of mechanical properties of structural metals was mainly achieved through the creation of increasingly complex chemical compositions. The complexity of this ingredient increases costs, creates supply fragility, and makes recycling more complex.As a relatively new metal processing technology, metal 3D printing provides the possibility to re-examine and simplify ...

T35 multi-core fiber grating and T103 multi-core fiber grating arrays can be engraved into all fiber cores in physical locations, or only onto certain fiber cores.They can also have the same wavelength, or they can have all different wavelengths at the same physical location along the fiber or at different physical locations along the fiber.T35 and T103 are very suitable for projects that require...
